From a quick look it still leverages viper integration for 12 Factor Apps, and since most of Coral’s features are well listed and detailed I’m going to make a presumption that Coral does not support reading environment variables (yet? Seems easy, maybe an opinionated decision?) not from external key value stores like Consul and Etcd. Client libraries for those would certainly cause a lot of extra dependencies.
